Basic Principle: A signal generator can be simply understood as an adjustable resistor. When used, it is connected in series with a wire, automatically adjusting the current to produce the set value. The wiring direction does not matter; it works normally in both directions. Quick Adjustment: Adjusted by a digital encoder. By turning the knob under digital encoding, the current position cycles leftward. Rotating the knob clockwise or counterclockwise directly adds or subtracts 1(X0.01/0.1/1/10mA) of current, making adjustments quick and simple.

More accurate adjustment:

1. Strictly add or subtract 1 when turning 1 grid, and the output changes a lot when the potentiometer is slightly twisted

2. The adjustment is faster. Press the encoder adjustment position to rotate left, and the 0.01~10-mA current can be directly adjusted for convenience and speed

3. Long-term stability. The encoder adopts CNC scheme to avoid the problems such as temperature, humidity, aging and wear of potentiometer, vibration and change of resistance value in long-term use of analog potentiometer

4. Higher precision and repeatability. As long as the potentiometer is touched (even if the product is not powered on), the output will change. The encoder is not powered on to turn the knob, and the output remains unchanged when the next power on. It is very suitable for multiple power on but the same test parameters are required

Frequently Asked Questions:

Q: What is the situation when there is no display on the product access circuit?

Answer: 1, check whether the power supply voltage is normal, whether it is between 14~30V;

2. Check whether the current circuit is broken;

3. Check whether the total resistance of the current circuit is too large (the resistance should be less than the power supply voltage/circuit current)

Q: Does access need to be directional?

Answer: No. The product has its own adaptive circuit, so there is no need to distinguish the direction, and it can work normally whether connected forward or backward.

Q: Can it be powered by batteries?

Answer: Yes. The module has a wide power supply voltage. As long as the battery voltage is within the nominal power supply range of the product, the battery can be used for power supply.
